Alongside the 12 ethnic groups living in Son La, smaller ethnic communities such as the La Ha, Kho Mu, and Khang have enriched the province's vibrant cultural landscape with their unique traditions. Over time, many of their cultural practices faced the risk of disappearing. However, thanks to the dedication of local artisans, the collective efforts of their communities, and, most importantly, the practical support and practical solutions of authorities at all levels, the cultural heritage of these smaller ethnic groups is being preserved, safeguarded, and promoted.

As part of the Thuan Chau Culture, Sports and Tourism Festival 2026, Thuan Chau commune on July 3 morning reenacted the traditional Xen Ban, a traditional festival that embodies the distinctive cultural identity of the Thai ethnic people.

Family is where moral values, healthy lifestyles, and cherished traditions are nurtured and passed on. In response to Vietnam Family Day (June 28) and the 2026 National Month of Action on Domestic Violence Prevention and Control, authorities at all levels, sectors, and localities across Son La province have implemented a wide range of communication and awareness-raising activities to promote the meaning and values of the family. These efforts aim to enhance the awareness and responsibility of individuals and communities in building happy families, which serve as the foundation for a happy and prosperous society.
